It wasn't moving when I pulled it out of the water, it seems that the hook merely lodged into it by accident, and it wasnt trying to take the bait. Does anyone know what it is?
This thing is bugging me too! There's something about it that rings a bell - I just can't quite get a handle on it.
An arm or tentacle of some sort of echinoderm is my best guess so far - maybe a sea cucumber (holothurian), but I can't find a picture to confirm that, though they do have tentacles.
It looks like a Thyone sp cucumber, were you fishing over a gravel bottom?
That's a much better suggestion and explains why the processes look so 'stiff'. Must stop looking at stuff late at night...
yes! thank you very much, i did some reading about sea pens and i believe it is a spiky sea pen!
Very intriguing, Tanjunjie,as it's such an odd creature! I thought this the only 'form to fit', but had a good look on the net & couldn't find any with spikes or the appearance of; so would be most interested if you found an actual spiky pen! ( & also whereabouts of this one)
I see spiny sea-pens do exist, with the "spiny sea-pen" Pteroeides spinosum found in Mediterranean (&in Greek Fauna & Flora).
In 'Marine Species' "reef corals of Indo-Malayan Seas" at http://species-identification.org/species.php?species_group=corals&menuentry=groepen&id=221&tab=multimedia has 11 images of the Genus Pteroeides (& description tab for text) & EOL at http://eol.org/pages/23155/media and http://www.wildsingapore.com/wildfacts/cnidaria/others/pennatulacea/spiky.htm some more.
